In addition, ecu6 constitutes torque reduces prohibition unit 53.Reduce the ecu6 of prohibition unit 53 as torque in vehicle deceleration,
Upshiftd with variator 11 and be judged as that driving means 14 tilt as condition to rear view of vehicle from displacement judging part 52, forbid electromotor
Torque control division 51 execution makes the torque that motor torque reduces reduce control.
Reduce the ecu6 of prohibition unit 53 when forbidding that torque reduces control as torque, forbid the ignition timing of electromotor 2
Change, thus forbid execute torque reduce control.
And, ecu6 constitute displacement power judging part 54, above-mentioned displacement power judging part 54 judge generation make driving means 14 to
The power that either direction in vehicle fore-and-aft direction obliquely conjugates.
In detail, the ecu6 as displacement power judging part 54 obtains the δ displacement ratio δ dp being calculated by displacement calculating section 50,
When this δ displacement ratio δ dp is more than 1, it is judged as creating the power making driving means 14 obliquely conjugate to rear view of vehicle.
In addition, ecu6 is when δ displacement ratio δ dp is 1, being judged as not producing makes driving means 14 incline to vehicle fore-and-aft direction
The power tiltedly conjugating.In addition, ecu6 is when δ displacement ratio δ dp is less than 1, being judged as creating makes driving means 14 to before vehicle
The power that side obliquely conjugates.
So in the present embodiment, calculate based on according to the relation of output axle rotary speed nd and driving wheel rotary speed nw
The displacement ratio dp going out and the displacement of δ displacement ratio δ dp judging-driving unit 14.
It is therefore not necessary to newly add shift sensor of displacement etc. of direct detection driving means 14, therefore, it is possible to prevent by
Manufacturing cost is made to increase in additional shift sensor etc..
In addition, being not the model cootrol setting the physics values such as the spring constant of engine mount 26l, 26r, but it is based on
According to the relation of output axle rotary speed nd and driving wheel rotary speed nw, the displacement ratio dp calculating and δ displacement ratio δ dp is carried out

Need to take a long time in the adaptation operation of each vehicle.
In addition, the ecu6 reducing prohibition unit 53 as torque does not conjugate and is judged as producing to be judged as driving means 14
Make driving means 14 be condition to the power that vehicle front obliquely conjugates, release and control is reduced to torque forbid.
The action carrying out with reference to the driving-force control apparatus of the above embodiments of the present invention constituting of Fig. 4 explanation.Additionally,
The action of following explanation is repeated within the short cycle.
First, ecu6 judges whether vehicle 1 slows down (step s1).Here, ecu6 is by vehicle-wheel speed sensor 21l, 21r
In the case that driving wheel rotary speed nw detecting reduces, it is judged as that vehicle 1 slows down.
In the case of being "Yes" in the judgement of step s1 (in the case of slowing down in vehicle 1), ecu6 judges δ displacement ratio δ
Whether dp is more than ormal weight (step s2).In this step s2, the ormal weight as comparison other is greater than 1 value.Thus,
Ecu6 judges whether δ displacement ratio δ dp is greater than more than 1 ormal weight.
In the case of being "Yes" in the judgement of step s2 (in the case of being more than ormal weight in δ displacement ratio δ dp), ecu6
Forbid that the torque of electromotor 2 reduces and control (step s3).
Next, whether ecu6 judging-driving unit 14 is upright and whether δ displacement ratio δ dp is less than 1 (step s4).At this
In step s4, in the case that displacement ratio dp is 1, ecu6 is judged as driving means 14 not in vehicle front or rear view of vehicle
Either one displacement, driving means 14 are upright.Here, δ displacement ratio δ dp means to create less than 1 makes driving means
14 power obliquely conjugating to vehicle front.
(driving means 14 are upright and the feelings less than 1 for the δ displacement ratio δ dp in the case of being "Yes" in the judgement of step s4
Under condition), ecu6 releasing forbids (step s5) to what the torque reduction of electromotor 2 controlled, and the flow chart of Fig. 4 is terminated.
On the other hand, in the case that the judgement of step s1, s2, s4 is "No", the flow chart of Fig. 4 is terminated by ecu6.
Timing diagram with reference to Fig. 5 illustrates the action role of ecu6 described above.Fig. 5 represents the row in vehicle 1
Sail the example trampled in the case of stopping of accelerator pedal 30.
In Figure 5, horizontal axis representing time, the longitudinal axis in figure from represent IS Idle Switch (in figure is designated as idling sw), combustion
The ratio of the rotary speed of input shaft 10 of material cut-out judgement, engine rotary speed and variator 11, displacement ratio dp, δ displacement ratio
δ dp, torque reduce illegal state, motor torque and driver's request torque.Additionally, driver's request torque is illustrated by the broken lines,
Become zero after the time tl.
In moment t1, when trampling of accelerator pedal 30 being stopped by driver and becoming the state of accelerator disconnection, idling
Switch becomes connection, and driver's request torque becomes zero.
In addition, in moment t1, due to implementing to disconnect corresponding fuel cut-off with accelerator afterwards, therefore allowing electromotor to turn
The torque of square reduces and controls, and by the ignition timing of electromotor 2 gradually to postponing side change, thus reduces motor torque and reduces
Engine load.
Then, in moment t2, the torque that the input shaft 10 of electromotor 2 and variator 11 has makes driving means 14 to drive
Temporarily obliquely conjugate to rear view of vehicle centered on axle 4l, 4r.Therefore, displacement ratio dp and δ displacement ratio δ dp increases.
Afterwards, in moment t3, in the value of the displacement ratio dp of driving means 14 be just and δ displacement ratio δ dp becomes ormal weight
During above positive value, it is judged as making due to the deceleration of vehicle 1 driving means 14 conjugate to rear view of vehicle, thus forbids torque
Reduce and control, therefore interrupt torque and reduce control.When forbidding that torque reduces control, forbid the change of the ignition timing of electromotor 2
More, therefore ignition timing reverts to the timing before delay.
Afterwards, in moment t4, when the value of displacement ratio dp is negative, it is judged as that driving means 14 conjugate to vehicle front,
Release the torque to motor torque and reduce forbidding of control, start again at torque and reduce control.Releasing, control is reduced to torque
When forbidding of system, postpones the ignition timing of electromotor 2 again, and motor torque is reduced due to the delay of ignition timing.
Afterwards, in moment t5, the value with displacement ratio dp is negative and δ displacement ratio δ dp is just correspondingly, is judged as driving dress

Piece installing 26l, 26r implement fuel cut-off to the moment t5 that vehicle front is taken a seat, therefore, it is possible to suppress rocking of driving means 14 to lead
The vibration of the driving means 14 causing.
As it appears from the above, according to present embodiment, possessing: displacement judging part 52, its judging-driving unit 14 is to before and after vehicle
Either direction in direction obliquely conjugates；And torque reduces prohibition unit 53, its when vehicle 1 slows down, with 11 liters of variator
Shelves and be judged as that driving means 14 tilt for condition to rear view of vehicle from displacement judging part 52, forbid engine torque control portion 51
Execution makes the torque that motor torque reduces reduce control.
According to this composition, when vehicle 1 slows down from conjugate judging part 52 be judged as driving means 14 to rear view of vehicle tilt
In the case of, forbid that so that the torque that motor torque reduces is reduced controls, therefore suppression driving means 14 are due to torque reduction control
System and from being significantly indexed to the inclination to vehicle front to the inclination of rear view of vehicle.As a result, carrying out when vehicle 1 slows down
It is also possible to the rocking of suppression driving means 14 in the case of the upshift of variator 11.
In addition, according to present embodiment, engine torque control portion 51 makes the ignition timing retard of electromotor 2 thus executing
Torque reduce control, torque reduce prohibition unit 53 forbid engine torque control portion 51 change electromotor 2 ignition timing thus
Forbid that torque reduces to control.
According to this composition, by forbidding the change of ignition timing thus forbidding that executing torque reduces control, therefore in vehicle 1
It is also possible to suppress rocking of driving means 14 in the case of carrying out the upshift of variator 11 during deceleration.
In addition, according to present embodiment, possessing displacement power judging part 54, above-mentioned displacement power judging part 54 judges whether to produce
Make the power that driving means 14 obliquely conjugate to the either direction in vehicle fore-and-aft direction, torque reduces prohibition unit 53 with by conjugating
Judging part 52 be judged as driving means 14 not displacement and be judged as creating from displacement power judging part 54 make driving means 14 to
The power that vehicle front obliquely conjugates is condition, releases and torque reduction control is forbidden.
According to this composition, driving means 14 not to the either direction displacement in vehicle fore-and-aft direction but upright and
Create in the case of making the power that driving means 14 obliquely conjugate to vehicle front, release and torque reduction control is forbidden,
Rocking and making vehicle 1 rapidly slow down therefore, it is possible to the suppression driving means 14 when vehicle 1 slows down.
" engine load is had to reduce as other embodiments it is also possible to add after step s1 of Fig. 4？" process.?
